Emmitt Holt's commitment to the Indiana basketball program Wednesday was the Hoosiers' last play in an offseason spent trying to shore up an unviable lack of post depth.

Whether it will work is very much uncertain.

Holt, a 6-8 power forward from Webster, N.Y., committed to IU after his official visit earlier this week. He averaged 19.8 points, 14.6 rebounds and five blocks in his final season at Schroeder High School.

The loss of Luke Fischer (transfer) and Noah Vonleh (NBA draft) left IU with few options inside when last season ended. Enter Holt, Tim Priller and Jeremiah April — all listed at forward or center, and all signed in the spring and summer.

April wasn't rated by Rivals, Scout or 247Sports at the time of his commitment.

Priller's high school coach listed Indiana, Wake Forest, Arkansas, Miami and Texas Tech among the schools recruiting him in the spring. He held off committing until then because going into his senior season, Priller's only scholarship offer came from Incarnate Word, a small private school in San Antonio.

Holt was planning to take a prep year at Vermont Academy and reclassify to 2015 before IU brought him to campus this week.

It's unfair and unwise to prejudge any of those three freshmen, beyond what we could see in Canada (where only Priller played). But expectations right now are light.

So Indiana has a roster stocked with six freshmen, four sophomores and no seniors. These are your Hoosiers, not just for now but for the foreseeable future.

Maybe that's not so bad.

In my experience, recruits don't automatically shy away from programs just because they lack scholarship space. So I don't think this closes the door on Indiana's 2015 recruiting efforts, despite a lack of seniors. National statistics suggest player transfers are as common now as they have ever been.

The more salient question addresses current personnel: What does Indiana need inside this year?

Based on what players were available on IU's preseason tour, general wisdom about this team was confirmed: Yogi Ferrell is its anchor, and the guards around him are his most important lieutenants. Indiana just added three players who will be listed as forwards or centers to a team that's as guard-driven as any coach Tom Crean has assembled in Bloomington.

Priller's future is likely tied to his 3-point shooting ability, but he admitted in Canada that he needs to be a better rebounder. His defense needs work, too.

April didn't play a minute in Canada because of an ankle injury.

Holt only set foot on campus this week.

Hanner Mosquera-Perea, Indiana's most experienced post player, missed all of the tour as well. He was left home because of "visa-related issues."

Indiana will hope its added depth can push Mosquera-Perea to improve, or that one of his new teammates is simply good enough to pass him. Otherwise, the burden on the guards will be heavy.

Michigan's outright Big Ten title last season is evidence that a team built primarily on its guard play can win hardware.

But that team included not just multiple NBA draft picks and the Big Ten Player of the Year, but also experienced forwards Jordan Morgan and Jon Horford. Neither was spectacular. Both were solid.

When the Hoosiers face Purdue's A.J. Hammons, or Wisconsin's Frank Kaminsky or Iowa's Aaron White, they will need that kind of presence, or risk getting overrun.

Is the future inside Mosquera-Perea? April? Holt?

That Indiana appears to be searching for more answers to that question in late August isn't the best sign.
